Le téléchargement de l'Image de Firebase de Stockage et de Base de données

Je veux mettre l'URL de téléchargement des images dans mon Firebase Base de données. Je peux télécharger l'Image dans le stockage, mais je ne peux pas comprendre comment obtenir l'URL dans ma base de données avec le reste de la "post".

@IBOutlet weak var titleText: UITextField!
@IBOutlet weak var authorText: UITextField!
@IBOutlet weak var mainText: UITextView!
@IBOutlet weak var dateText: UITextField!
@IBOutlet weak var myImageView: UIImageView!
var ref:FIRDatabaseReference?
override func viewDidLoad() {
super.viewDidLoad()
ref = FIRDatabase.database().reference()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
@IBAction func uploadImage(_ sender: Any) {
let image = UIImagePickerController()
image.delegate = self
image.sourceType = UIImagePickerControllerSourceType.photoLibrary
image.allowsEditing = false
self.present(image, animated: true)
{
//after its completed
    }
}
@objc(imagePickerController:didFinishPickingMediaWithInfo:) func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
{
if let image = info[UIImagePickerControllerOriginalImage] as? UIImage
{
myImageView.image = image
}
else
{
//error
    }
self.dismiss(animated: true, completion: nil)
let storageRef = FIRStorage.storage().reference().child("myImage.png")
if let uploadData = UIImagePNGRepresentation(self.myImageView.image!){
storageRef.put(uploadData, metadata: nil, completion:
{
(metadata, error) in
if error != nil {
print("error")
return
}
print(metadata)
//how do I put the download URL in the metadata into my database

}  
)
}
}
@IBAction func addPost(_ sender: Any) {
if self.titleText.text != "" && self.authorText.text != "" && self.mainText.text != "" && self.dateText.text != ""
{
ref?.child("Posts").childByAutoId().setValue(["Title": titleText.text,"Article": mainText.text, "Author": authorText.text, "Date": dateText.text, "myImageURL": myImageURL])
//the myImageURL part is where I get an error

self.performSegue(withIdentifier: "post", sender: self)
}
else{
let alertController = UIAlertController(title: "Oops!", message: "Field left blank", preferredStyle: .alert)
let defaultAction = UIAlertAction(title: "Ok", style: .cancel, handler: nil)
alertController.addAction(defaultAction)
self.present(alertController, animated: true, completion: nil)
}
}
}

    Organiser votre upload et save funcs comme ceci:

    func uploadMedia(completion: @escaping (_ url: String?) -> Void) { 
let storageRef = FIRStorage.storage().reference().child("myImage.png")
if let uploadData = UIImagePNGRepresentation(self.myImageView.image!) {
storageRef.put(uploadData, metadata: nil) { (metadata, error) in
if error != nil {
print("error")
completion(nil)
} else {
completion((metadata?.downloadURL()?.absoluteString)!)) 
//your uploaded photo url.
            }
}
}

    Prochaine connectez-vous à FIRDatabase et l'enregistrer sur votre nœud.

     @IBAction func addPost(_ sender: Any) {
if self.titleText.text   != "" && self.authorText.text != "" 
&& self.mainText.text != "" && self.dateText.text   != "" {
uploadMedia() { url in 
guard let url = url else { return }
ref?.child("Posts").childByAutoId().setValue([
"Title"      : titleText.text,
"Article"    : mainText.text, 
"Author"     : authorText.text, 
"Date"       : dateText.text, 
"myImageURL" : url!
])
}
}

    Vous pouvez également regarder ma réponse sur le téléchargement des données et l'enregistrement de l'URL de base de données

    Espère que cela aide

    Alors, comment puis-je le mettre dans ma base de données? ref?.enfant("Messages").childByAutoId().setValue(["Title": textedetitre.texte,"Article": mainText.texte, "Auteur": authorText.texte, "Date": dateText.le texte ])
    Je vais mettre à jour ma réponse
    fait:)
